Question 4: An ideal incompressible fluid flows at 0.252 m/'s through a 44-mm diameter cylindrical pipe. The pipe widens to a square cross-sectional area that is 5.5 cm on a side. Assume steady flow throughout the system. (a) What is the speed of the fluid through the square section of pipe in m/s? (b) What is the volume flow rate in m 3/s? (c) Calculate the change in pressure P2-P1 between these two points? (Use Bernoullis)
